wAR'P FOR PATTERN-MAKING.

QPECIPICATION forming part of Letters Patent No. 383,182, dated May" 22, 1888.

Application filed March 18,1885. Serial No. 159,286.

To all whom it may concern:

Be it known that 1, CHARLES H. LANDEN- BERGER, a citizen of theUnited States, residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Warps for Pattern- Making, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to warps for patternmaking; audit consists in an improved warp, as hereinafter described, of less thanfive yards in length, having various colors or qualities of yarn therein, the same being formed in an eX- peditious manner, avoiding the necessity of using a large number of spools of each color or quality and the great loss of time in making short warps on the warping machinery commonly in use, or the changing of colors or qualities in the pattern-loom while weaving patterns by the slow process of substituting and tying in each separate thread.

Referring to the drawings, Figure 1 represents the relative position of the selvagebands, the lease ends, and the weft-thread in a pattern warp composed of two different threads embodying my invention. Fig. 2represents the manner of uniting different warps embodying my invention, so as to have them in continuous lengths on the warp-beam.

In carrying out my invention I discard the usual method of employing warping machincry and use instead any kind of broad weaving-loom having a sufficient number of shuttleboxes. There being no warp in the loom in the space between selvages, the threads carried by the shuttle from one side of the loom to the other do not serve their ordinary purpose as weft, but remain stretched from one selvage to the other, as shown in Fig. 1 of the drawings. Nhen cut out of the loom these threads are intended to be used as the warp for making patterns in a pattern-loom in the manner hereinafter to be shown.

A group of warp-threads is drawn through the harness and reed at each side of an empty loom, which I will call for convenience the warp-loom, forming the selvage-bands A and B. In addition to the groups of warpthreads A and B, forming the selvage bands, I use for lease ends two threads of heavy yarn, O c D d, drawn through the harness and (No specimens.)

placed in the reed about eight inches inside of the selvage band on both sides of the loom, the harness being so arranged as to cause said selvage and lease ends to be operated in a plain one-and-one weave.

Each shuttle of the warp-loom carries one of the colors or qualities required in the pattern-warp, and is thrown forward and across the loom in the order determined by the pattern designed to be made. Each thread a so thrown across the loom floats from one side to the other, only held in place by being interlocked by the selvagethreads, as shown in Fig. 1.

In order that the threads of the patternwarp shall occupy the correct space designed for them in the subsequent process of weaving it is necessary to actuate the take-up apparatus of the Warp-loom accordingly. For instance, if fourthousaud ends are required in a warp which is afterward to be set in the harness of a loom one hundred to the inch, the take-up apparatus on the pattern-warp loom should be arranged to put in one hundred picks per inch. After the required number of threads have been thrown across the warploom the pattern-warp will be completed, and only needs to be cutout of the loom to be ready for the next operation.

In handling the pattern-warp through the succeeding operations the sclvage-bands will be found to be of great service, as they keep the warp-threads always in place and the warp at the required width. One of the selvage-bands may now be fastened across a warp-beam and the warp carefully rolled on the beam, as.

manner a third or any number of warps may be put'on the heam,which is then taken to the pattern-loom,the warpthreads drawn through the appropriate harness, and all the different warps woven out.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a. new article of manufacture, a warp for pattern-making, having a selvagc-band at each end, substantially as and for the purpose set forth.

2. A warp for patternniaking, having selvage-bands and lease-threads, substantially as and for the purpose set forth.

3. A Warp composed of continuous threads alternating from one end to the other of its length, and at each end being interlocked with threads crossing the same at right angles and forming a selvage-band at each end, substantially as described.
